OF BUFFALO, NEW YORK.

FORGE.

Lttll llfi Application filed July 24, 1915.

To all whom it may concern:

Be it known that I, HENRY W. lVnNDr, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Forges, of which the following is a specification.

This invention relates to blacksmiths forges, more particularly of the portable type, which are adapted for use on railroads, bridges, structural steel works and elsewhere, necessitating transportation of the forge from place to place. The invention is not, however, necessarily restricted in application to this type of forge.

The objects of the invention are to so mount the blower on the forge that it can be quickly and easily reversed and shifted from one to the other side of the hearth in position to be readily operated either by a righthanded or left handed man standing at one or the other side of the forge; also to removably mount the blower and the twyer pipe so that they can be readily disconnected from the hearth to facilitate the packing and transportation of the forge and in such a manner that theblower is rigidly and securely supported by the twyer pipe without the necessity for a separate supporting arm or bracket.

In the accompanying drawings, consisting of two sheets Figure 1 is a side elevation of a forge embodying the invention. Fig. 2 is a fragmentary sectional elevation of the hearth and twyer pipe on line 2-2, Fig. 4. Fig. 3 is a plan view of the twyer pipe and the supporting flange therefor, partly in section in line 33, Fig. 2. Fig. 4: is a plan view of the forge with the hood removed,-

showing the blower in position at one side of the hearth to be operated. by the left hand. Fig. 5 is a similar view, showing the blower reversed and in position at the other side of the hearth to be operated by the right hand.

A represents the hearth or pan and B, the hood of a forge, which, with the exception of the mounting of the blower and twyer pipe thereon, may be of any usual or suitable construction. In the forge shown, the hearth is supported by upright legs a at the corners thereof and is provided with the usual depressed fire pot G with which the twyer pipe connects.

E represents a twyer connected with the fire pot and F a twyer pipe or blast pipe Specification of Letters Patent.

which extends from the twyer outwardly beneath the hearth and is provided with an outer end portion which preferably extends upwardly at an angle of about forty-five de grees, and on which the blower is mounted and supported. The twyer and twyer pipe are preferably cast in a single piece which is removably secured in position and consti tutes the sole support for the blower. The twyer is reinovably and rotatably connected to the lower end of the fire pot C by suitable means, such for-example, as a segmental circular plate 9, which is bolted to the lower end of the fire pot and has a flange that projects under an outwardly projecting rim flange g on the twyer. The outer end of the twyer pipe is supported as by a bolt or securing device H, which extends through the pipe and through a segmental slotted plate h, which is suitably secured on the hearth and the slot h of which is curved concentrically with the center of the twyer. The bolt H is provided with a hand nut 7L2, by means of which the pipe can be rigidly clamped to the slotted supporting plate h. The twyer is adapted to be turned to different angular positions on its connection with the fire pot so that by loosening the securing bolt or device H, the pipe can be swung about the axis of the twyer as a center from a position in which its outer end extends adjacent to one side of the hearth, as shown in Fig. l, to a position in which its outer end extends adjacent to the opposite side of the hearth, as indicated in Fig. 5. The pipe can be rigidly secured in either of these positions, or in any desired intermediate position by tightening the nut h Any other suitable way of mounting and securin the twyer and blast pipe so that the pipe can be swung from one to the other side of the hearth and secured may be employed.

The blower which is shown at I, may be of any suitable construction adapting it to be reversed on the outer end of the twyer pipe so as to locate its operating crank handle at one or the other side of the blower. The blower shown is provided at one side thereof with an operating crank handle 73, secured to a shaft located substantially midway between the front and rear edges of the blower casing, and the blower casing connects with the twyer pipe F by a discharge connection In, which extends radially from the casing mid-way between the opposite lift edges thereof, and is detachably and reversibly connected to the end of the twyer pipe. By reason of this arrangement, the blower can be secured on the twyer pipe with its operating handle located at either the right or the left hand side of the blower, and the handle will occupy corresponding positions relative to the hearth at opposite sides of the blower, and will be the same distance from the hearth so that it can be operated with equal facility in both positions. The blower can be detachably secured to the outer end of the twyer pipe, so as to permit it to be readily disconnected and reversed by any suitable means, as for example, by providing the discharge connection is of the blower with a dovetail or flanged end Z, which fits in a cooperating dovetail or flanged clamp Z, on the upper end of the twyer pipe having a movable jaw or mem: ber adapted to be moved to clamp and release the blower by a nut Z and bolt Z The nut Z can be, if so desired, provided with a handle for turning the same so as to avoid the necessity for a wrench or other tool.

In forges having a small or round hearth it is not necessary for the pipe to swing to the side, as the blower can be reversed on the twyer pipe to locate its handle at one or the other side of the blower, and the handle conveniently operated with the pipe in a position centrally between the sides of the hearth, but when the invention is used in connection with forges having a rectangular or large hearth, the twyer pipe is preferably mounted to swing from side to side of the hearth as explained, so as to place the blower near either side of the hearth where it can be more easily reached.

I claim as my invention:

1. In a forge, the combination with a hearth, of a blower, and an air pipe which connects the blower to the hearth and is arranged to move laterally to different positions relative to the hearth for placing the blower at one or the other side of the hearth, said blower being reversibly connected to said pipe.

7 In a forge, the combination with a hearth, of a twyer pipe connecting with said hearth and extending outwardly beyond the same, and a blower having a casing provided with a discharge connection which is secured to the outer end of said twyer pipe by a connection adapting the blower to be reversed about the axial line of the outer end of said twyer pipe for locating the operating handle of the blower at either side of the blower.

8. In a forge, the combination with a hearth, of a twyer pipe connecting with said hearth and extending outwardly therefrom at an upward inclination and a blower having a casing provided with a discharge connection which extends therefrom substantially radially at the same inclination as the twyer pipe and is secured to said twyer pipe by a connection adapting the blower to be reversed about the axial line of the outer end of pipe for locatingthe operating handle of the blower at either side of the blower.
